Apps on iPhone not updated after applying App update on my iMac/iTunes
I have an iPhone 4s that i connect to my iMac (OS X). \
Issue: After I launch iTunes on iMac and update all app's - those updates are NOT applied to my iPhone 4s. Started when I bought the new iMac and moved to that desktop iMac. There iPhone and my apps on iMac/iTunes are never in synch. I have to update my iPhone app's via Wifi
Sure it has something to do with profile - this phone was originally setup on a Windows PC which I retired and moved 100% over to iMac.
How do I go about debugging resetting so my phone and iMac iTunes are in lock step/synch?
Thanks,
REM
iPhone 4S, iOS 8.1
